I lost my data. However, I have the plot of data. I realize that x data should be shifted of one unit. If I had the data, it would have been easy to change the code and do the shift by doing something as: x_new = x_old + ones(size(x_old)). But, unfortunately, it is not the case.
Do you know how the data can be shifted on the figure ?
thanks in advance.

Suppose that i have a figure
fig = figure,
ax = axes(fig);
Now i dont know what is my data
Suppose that i have just the figure, let us extract data from figure
Line_Obj = findobj(gca,'Type','Line')
X = Line_Obj.XData;
Y = Line_Obj.YData;
Now i add an offset in it
hold on,plot(gca,X,Y+0.5)
Remember that this demonstration is for Line object, if your plot contains any other object like scatter, histrogram etc, you have to change it in findobj


if you dont want to plot it, just use copyobj for that purpose
h = copyobj(Line_Obj,gca);
h.Color = 'g';
h.YData = h.YData-0.4;
